Benefits of technology

[0011] An object of the present invention is to provide a universally applicable and easily operated irradiation device of the type described above with which a wide variety of biological structures within a living organism can easily be influenced in a targeted manner, and with which, in particular, viruses, bacteria, fungi, carcinogenic cells, or other pathological sites can be destroyed without significantly damaging other biological structures inside the organism.

Problems solved by technology

Consequently, the system can be excited by small mechanical or acoustic oscillating forces in a very narrow frequency band close to or equal to the resonant frequency, inducing a resonance in the target structure that has a strong influence on the target structure, leading to its destruction.
The energy remaining in the structure can influence the functioning of the structure, and can even result in the destruction of the structure.

Embodiment Construction

[0045] The irradiation device 10 shown in FIG. 1 can be used for the whole-body irradiation of a person. For this purpose, irradiation device 10 has a transmission antenna 50 having a cylindrical structure—in this case, a birdcage antenna 50. The transmission antenna 50 is situated in a tube-shaped housing 60 having a cylindrical interior radiation space B, in which the radiation subject O, i.e., the person to be irradiated, is positioned on a platform. The precise design of housing 60 and the transmission antenna 50 is explained in more detail below.

[0046] In order for the transmission antenna 50 to emit the radio-frequency electromagnetic radiation S into radiation subject O, this antenna is connected to a frequency generator 20. This is an RF generator 20 which is preferably able to generate RF signals from the kilohertz range into the gigahertz range. A component of this frequency generator 20 is a frequency synthesizer 21 which is capable of producing an electrical alternating...

Abstract

An irradiation device for irradiating a living organism with electromagnetic radiation in order to influence biological structures inside the organism has a frequency generator that has a frequency synthesizer for the production of electromagnetic radiation having a defined frequency pattern, and a transmission antenna that is fashioned such that during operation the electromagnetic radiation is emitted essentially into a particular radiation volume. In addition, the irradiation device has an interface for acquiring structure-specific data for identifying a biological target structure that is to be influenced, a frequency pattern storage unit in which defined resonant frequency patterns allocated to various biological structures are stored, a frequency pattern selection unit for selecting a resonant frequency pattern from the frequency pattern storage unit on the basis of the acquired structure-specific data, and a control unit for controlling the RF generator in such a way that a subject to be irradiated, situated in the radiation space, is exposed to electromagnetic radiation having the selected resonant frequency pattern at a particular intensity and for a particular duration of irradiation.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an irradiation device for irradiating a living organism with electromagnetic radiation in order to influence biological structures inside the organism. In addition, the present invention relates to a control device for such an irradiation device. [0003] 2. Description of the Prior Art [0004] Shortly after the discovery of electromagnetic waves by H. Hertz at the end of the 19th century, attempts began to be made to find therapeutic uses for radio-frequency or high-frequency electromagnetic fields and the heat induction they can produce. A relatively new technology is known as electromagnetic tomography or microwave tomography, which is regarded as having enormous potential in the field of medicine. This technology is explained, for example, in EP 0 928 157 B1. There, a spectroscopic method is described in detail that enables rapid, non-invasive imaging of various physiological tissue...
